Caption:
Used for locating radar pulse beacons - often used for drops to resistance forces. Rebecca / Eureka is a simple system designed initially to assist in the delivery of supplies to the Army or Resistance in occupied Europe. The system expanded into blind homing and approach aid for aircraft. Much of the credit for the development of this system must go to Dr.R.Hanbury-Brown and J.W.S.Pringle of the TRE (Telecommunications Research Establishment);
